Lock screen not responding when charging topic

I have a N9005, and i discovered that when the charger is connected, it will be very hard to almost impossible to unlock the lock screen with swipe.

I can see the animation when swiping over the screen, and have since disabled the animation to no avail, but the screen won't unlock.

Occasionally I may succeed in unlocking, if I hold my finger on the screen for a few seconds, then swiping with a slight pressure. Once unlocked swipes on the home screen will work, though sometimes with little stuttering.

I have stock rom and recovery, rooted using the Towel root method.

Once I disconnect the charger everything is back to normal.

Any advice?
